Definitions
- the invention generally relates to regulators and more specifically to regulators having an adjustable fixed pressure relief assembly.
- Fluid flow from one location to another location is often controlled by a valve or regulator.
- the valve or regulator may be designed to maintain certain flow rates or fluid pressures within a predetermined range.
- a regulator includes an actuating mechanism that controls a location of a valve plug with respect to a valve seat. The valve plug and valve seat cooperate to control fluid flow through the valve or regulator.
- a regulator valve may control the flow of natural gas or propane out of a tank.
- the pressure of the natural gas or propane will also increase. If the pressure exceeds a design pressure for the regulator or the tank, material failure may occur, causing danger to lives and property.
- most regulators attached to tanks have some sort of pressure relief device either attached to the tank or on the regulator itself.
- a pressure relief assembly may be located in an actuator housing.
- the pressure relief assembly includes an actuator stem, a diaphragm plate, a relief plate, and a diaphragm at least partially disposed between the diaphragm plate and the relief plate.
- a relief spring is disposed between a relief spring seat and the relief plate, the relief spring biasing the relief plate towards the diaphragm, a releasable seal being formed between the diaphragm and the relief plate.
- the fixed assemblies include a relief spring seat that is fixed to the actuator stem and not movable relative to the actuator stem.
- Adjustable assemblies include an adjustable relief spring seat that is movably attached to the actuator stem with a compression nut.
- the adjustable relief spring seat may be moved along the actuator stem to adjust a bias generated by the relief spring.
- Adjustable assemblies are more flexible and may be adapted to different relief pressures.
- adjustable assemblies are more susceptible to failure as the relief spring seat may unexpectedly move along the actuator stem if the compression nut becomes loose. For this reason, adjustable assemblies are less reliable and some regulations prevent the use of adjustable assemblies for certain uses.
- a pressure relief assembly may include an actuator stem having a plurality of retaining grooves.
- a relief plate may be operatively connected to the actuator stem and a diaphragm plate may be operatively connected to the actuator stem.
- a diaphragm may be least partially disposed between the relief plate and the diaphragm plate.
- a relief spring seat may be releasably attached to the actuator stem at one of the plurality of retaining grooves. The relief spring may be adjusted by moving the attachment point from one retaining groove to another retaining groove.
- a regulator may include a pressure relief assembly and a valve body having a fluid inlet and a fluid outlet.
- An actuator may be operatively connected to a valve plug by the actuator stem, the actuator moving the valve plug within the valve body to control fluid flow through the valve body.
